The first TV series broadcast on TV Asahi's "Friday Night Drama" slot from July 4, 2003 until September 19, 2003, and garnered an average rating of 12.0%, reaching a high point of 14.1% according to the Kantō Area Video Research group, the highest rating of any show in the "Friday Night Drama" slot. During the final episode of the first series, viewers were told that Tadano and Moriwaki were going to take a 15-month vacation traveling around to various onsen across Japan. A special titled Tokumei Kakarichō Tadano Hitoshi Returns was aired on December 22, 2004, just over 15 months since the final episode of the first series.

On January 14, 2005, the second series began airing, running through March 18, 2005. According to the Kantō Area Video Research group, the series achieved a 16.0% rating with the episodes airing on February 11 and 18. The final episode garnered a rating of over 20% in its timeslot, due largely to the main character, Tadano, collapsing during the episode due to being overworked. On August 7, 2005, the second special was aired, titled Nerawareta Serebu na Onna-tachi. The special garnered a 19.3%, the second highest rating ever for a drama, and making it the most popular drama aired between August 1 and 7.

The third series began airing January 12, 2007.

While in the original manga Tadano is a "lone wolf", in the TV series he works in combination with Moriwaki, a character created for the TV series. Moriwaki has now made his appearance in the original manga.

Based on a comic by Kimio Yanagisawa, Tokumei Kakaricho Tadano Hitoshi is a story about salaried worker who leads a double life as inept manager at the company, but moonlights as a heavy for the chairman of the company, investigating corruption within and outside of the company.

Jin Tadano (Katsunori Takahashi) is an assistant manager of operations department. Most people calls him Hitoshi Tadano because Jin can be read as Hitoshi, and this rhymes with Tadano Hito (an ordinary person). He pretends to be useless employee, but that's just a guise to hide his true function within the company. He's really like a ninja working for the chairman of the Denoudo corporation, always on a secret assignment to protect the people and the projects that the company is involved with. He is looked down by most of his fellow employees as useless oaf, but few girls likes him for who he is. This includes the secretary of the chairman Noriko Tsubouchi (Atsuko Sakurai), TV broadcaster Mayuko Shinmizu (Rieko Miura), and his coworker Kazue Yamabuki (Yuri Ebihara).

In each episode he's involved in solving corruption, murder, kidnapping, and all sorts of problems the company and its clients gets involved with. The program is made for adult audience, and was aired during late night time slot. The theme and characters that appears in the story reflects this. There're humor, action, some sexuality, and intrigue that makes this an excellent drama series coming out of Japan.
